HCG Level Calculator

Many women want to know what the average HCG level is in early pregnancy and what the normal rate of increase is. In general, pregnant women who have an HCG level lower than 1,200 mlU/ml can expect their HCG numbers to double every 48 to 72 hours. As the pregnancy gets further along and the HCG level gets higher, the rate of increase slows down. To find out if your HCG numbers are rising normally, just input your data in our calculator and our chart will track your data.

HCG, also called the “pregnancy hormone”, is the abbreviation for Human Chorionic Gonadotropin. It is produced by the cells in the placenta as soon as the fertilized egg is implanted on the uterine wall. A woman’s HCG level can be first tested about 11 days after conception through a blood test. A urine test can also be done to check the levels in about two weeks after conception.

Most women want to know what the normal HCG levels in pregnancy are.  However, there isn’t really a single HCG level for every week or month of pregnancy. Every woman can have a different HCG level compared to others at the same stage of pregnancy. The ranges of levels per stage are quite wide. For example, at 6 weeks LMP (Last Menstrual Period), the range is from 1,080 – 56,500 mIU/ml. What is truly important about these numbers is the rate of increase or the change in level that the woman experiences in her early pregnancy.

How fast can you generally expect your HCG levels to increase during early pregnancy? For women who have an HCG level lower than 1,200 mlU/ml, their levels will double every 48-72 hours. For HCG levels between 1,200 to 6,000 mlU/ml, it takes about 72-96 hours to double. HCG levels that are over 6,000 mlU/ml take much longer to double, taking as long as 5 days or more.

Monitoring the progress of your HCG levels is no longer important once you reach 6,000 mlU/ml because it is no longer a significant indicator of how well your pregnancy is going. By this time, the rate of increase will slow down and, after a while, will start to decline until it plateaus. Once you are 6-7 weeks pregnant, the best way to test the health of your pregnancy is through a sonogram to confirm that there is already a fetal heartbeat present. Once there is, testing your HCG level is no longer necessary.
